廖老师，你问中FileReader直接指定编码格式，但是我这通过不了。网上查资料也显示不能直接指定

网上资料还有啥能比JDK文档更权威的呢？

哈哈，廖大用的是最新版本的JDK13，你估计用的8吧

JDK版本低了吧

带 Charset 参数的构造函数在 Java 11 中加入。Java 8 中可以使用 InputStreamReader 包装 FileInputStream 自行构建。

#6 Created at ... [Delete] [Delete and Lock User]

java 8 可以这样指定

InputStream stream = new FileInputStream("D:\\");
FileReader fileReader = new  InputStreamReader(stream,"UTF-8");
